The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

In conjunction with Fig. 1, shown in Figure 2, submerged water screening machine of the present utility model mainly includes driving machine 1 that main shaft 3, drive shaft rotate and the cartridge type sieve 7 of the heavy water dusting cover segmentation of rotating with main shaft and the cartridge type sieve 5 of classifying screen segmentation, wherein:

Main shaft 3 is and is horizontally disposed with, and an end of its charging leaves safety margin to give charging equipment, and the function of avoiding the direct impacting shaft bearing of material is arranged with oblique cantilever support 8 supportings, and an end of discharging is with a structural formula bracket supports 2.The shared bearing block of the discharge end axle of the output shaft of driving machine and main shaft, and be designed to floating type connection, with the axle of protection driving machine.

The cartridge type sieve 7 of heavy water dusting cover segmentation is positioned at the front portion of main shaft, and its front end taps into hopper 9.For the material that enters in the screening machine can be distributed on the screen cloth uniformly, each cartridge type sieve of this screening machine all is designed to multiple-piece cloth spiral stator.Spiral stator 71 in the cartridge type sieve 7 of heavy water dusting cover segmentation is fixed on the crossbeam that parallels with main shaft 72, and crossbeam is fixing by a backgauge dish 74 and a transition tie-plate 75 again.Backgauge dish 74 is arranged on the inner front end of cartridge type sieve, is fixed on the main shaft 3.Use the backgauge dish can make material directly not enter cartridge type sieve deep.Transition tie-plate 75 is arranged on the cartridge type sieve 7 of heavy water dusting cover segmentation and the transition position of the conical cylinder type tube 6 of screening and dewatering lifting section, is fixed in main shaft 3.The cantilever end of each stator all be connected in one with stator on the end plate 76 that equates of external diameter, end plate is installed in the charging port.Be coated with dusting cover and divide screen cloth 73 on the cylindrical of stator, the aperture of screen cloth is good with 2～6.3mm.The cartridge type of the heavy water dusting cover segmentation of Gou Chenging sieve profile is cylindrical thus.Washed-out sand pond 10 is arranged on the below of cartridge type sieve, and the bottom of cartridge type sieve is immersed in the water.

For being raise, material leaves the water surface and dehydration, sieve the taper cartridge type sieve 6 that has designed screening and dewatering lifting section between 5 at the cartridge type sieve 7 of heavy water dusting cover segmentation and the cartridge type of classifying screen segmentation, each spiral stator 61 be designed to reducing not the displacement form (under the situation of needs, also can be designed to reducing, varying pitch, change blade radial height), be fixed on the cone guide vane seat 62 that fixes with main shaft, dusting cover divides on the cylindrical that screen cloth 63 is coated on the spiral stator.The bottom of taper cartridge type sieve is immersed in the water in washed-out sand pond, and the afterbody that keeps the taper cartridge type to sieve exceeds the horizontal plane in washed-out sand pond.Like this, not only make in the screen cloth material finish the screening reach of rolling, also in reach and be raised height, finish the function that thick material is lifted out the water surface and dehydration.The dusting cover section arrives this section extremely, and material is finished the two-stage sub-material.

The multi-stage screening of different gradation realizes that by the cartridge type sieve 5 of classifying screen segmentation the cloth spiral stator 51 of this section cartridge type sieve is designed to cylinder (or cone), is fixed on the stator seat 52, coats the bigger screen cloth in aperture 53 outward.This section theory of mechanics is identical with sunk dusting cover segmenting principle, and only the scalping segmentation does not exist the characteristic of material adhesion and the pollution of dust.So this section does not design the submerged water screening, the afterbody material is discharged from the discharge bucket that is connected on cartridge type sieve rear end mutually.And can suitably add the helical feed section for what needs were carried certain distance.

Operation principle is as follows: drive each cartridge type sieve rotation with motor-driven reductor (hydraulic motor acceleration and deceleration device or directly drive with the large torque low speed hydraulic motor); Material enters the cartridge type sieve 7 of heavy water dusting cover segmentation by feed hopper 8 (or other feed gearbox).Enter the material between each spiral stator, under the effect of water, fines loses adhesion rapidly, sieve screen apertures is passed in downslide, and remainder turns over an angle with screen cloth and stator under the usefulness of frictional force is used, and be raised, the passage of material between the blade of the gravity effect lower edge downslide (more having increased the shatter value of material) of rolling then, thus material has also produced moving along the screening machine axis direction.So circulation arrives the end of the taper cartridge type sieve 6 that promotes the screening and dewatering section, finishes the dusting cover operation break-down, and screening efficiency can reach more than 90%.Then, by the cartridge type sieve 5 of classifying screen segmentation, classification falls in the hopper 11 material again, and the afterbody material is discharged from the discharge bucket 4 of cartridge type sieve rear end.
